Final answer:
Nonsense words in poetry, like those in Lewis Carroll's 'Jabberwocky,' serve to engage the reader's imagination and contribute to the poem's rhythmic and aesthetic experience, rather than conveying literal meanings.
Step-by-step explanation:
The question suggests that "ugglewump" is a nonsense word in English, comparable to those used by Lewis Carroll in the poem "Jabberwocky." Just as in this poem, nonsense words are employed to evoke imagination and rhythm rather than to convey a conventional meaning. Humpty Dumpty's attempt to provide literal meanings to these words, as he does for Alice, actually detracts from the poem's essence and imaginative richness. Nonsense words contribute to the narrative structure and aesthetic qualities of a poem, allowing readers to engage creatively with the language. 'Jabberwocky' demonstrates that poetry is more than just its literal meaning; it is about the experience it provides through its unique structure and the harmonization of sounds. Cleanth Brooks' view emphasizes that by understanding the structure of a poem, just as a ballet or a musical composition, we recognize how critical it is to preserve the original form rather than seek paraphrased explanations which can diminish its beauty and negate its intended effect. Thus, the importance lies in appreciating each poem for its overall effect on the reader—including its intrinsic rhythm and allowability for personal interpretation.
